The
first thing to wear out on your CNC Machining Center is often
the drawbar!
Belleville springs provide
the only force that holds the tools in the spindle while cutting
and they are often the first thing that wears out on a CNC
Machining Center.
Drawbars can have over 140
Belleville springs in the stack. Just the slightest wear on
each spring will have a big affect on clamping force, causing
chatter, bad finishes, reduced cutter life, and scrapped parts.

Left
unchecked, a tool may eventually pull out during a cut, damaging
the spindle, cutter, arbor, and fixture. Machines are never
the same after a crash.
Problems
with repeatablility, bad finishes, and short cutter life can
be frustrating and difficult to diagnose. Up in the spindle
and out of sight, drawbars seldom get the attenetion they
deserve. To check it requires a special tool designed just
for that purpose. Previously these tools cost many thousands
of dollars, but now you can check your spindle for a fraction
of that cost.
The
Clamprite Gage simulates a tool in the spindle and checks
the drawbar in less than a minute. It has no batteries, clumsy
cables or delicate electronics. The pressure gauge reads directly
in pounds/force, so there are no conversions or calculations.
Hundreds
of shops in the US. and around the world use the Clamprite
Gage. Customers often say it paid for itself the first time
they used it.
